Episode Title:
Itona Horibe Time.
Episode Description:
Despite Itona's increased deadliness, Koro-sensei manages to evade his attacks and defeat him. Just then, Itona starts reeling from the effects of his tentacle implants, which he had been keeping under control due to Shiro's treatments. Shiro leaves after deeming no further use of Itona, who later goes on a rampage and starts destroying cell phone shops. As Koro-sensei tries to reason with Itona, Shiro attacks Koro-sensei and capture Itona. Shiro lures Koro-sensei into another trap, but the students arrive on the scene to rescue Koro-sensei and Itona, forcing Shiro to retreat. The students soon learn that Itona was allegedly abandoned by his parents after their electronics company went bankrupt. After Takuya Muramatsu, Taisei Yoshida and Kirara Hazama each fail to cheer up Itona, Ryōma Terasaka manages to calm down Itona, allowing Koro-sensei to safely remove the tentacle implants and enroll him as an official student of Class 3-E.
